ChoiceSet expanded style does not show as radio

The style attribute of ChoiceSet does not influence the appearance of the rendered object. The expected behavior is for the choices to appear as a group of radio buttons. The current behavior shows the rendered object as a dropdown for both compact and expanded values.

Examples

From the Todoist Integration Examples Lorem Ipsum example:

const choiceSet = new ChoiceSetInput()
choiceSet.id = 'Input.Choice'
choiceSet.style = 'expanded'
choiceSet.choices = [
    new Choice('1'),
    new Choice('2'),
    new Choice('3'),
]
choiceSet.defaultValue = '1'

card.addItem(choiceSet)

From an integration I'm currently working on:

{
  "type": "Input.ChoiceSet",
  "id": "dayChoice",
  "label": "Expires",
  "style": "expanded",
  "choices": [
      {
          "title": "Today",
          "value": "today"
      },
      {
          "title": "Tomorrow",
          "value": "tomorrow"
      }
  ]
}

Start by tracing ChoiceSetInput rendering and how its style attribute is handled. Verify the behavior using the TypeScript and JSON examples in the issue; done means expanded choices render as radio buttons while compact choices remain a dropdown.
